I'm having a problem (with Qt themes, but that doesn't matter here), found a couple of threads with some advice, tried it, and I find that it doesn't work with very recent Qt (>= 5.11).
I wanted to add a brief comment so that other users could be advised that the answers might no longer be valid...

I was trying to install mysql-server and while trying to set a password I messed up the debian.cnf file and then deleted /etc/mysql hoping that dpkg-reconfigure would recreate it.
Now dpkg-reconfigure is giving an error regarding missing cnf files in /etc/mysql
Tried reinstalling mysql-server i...

If there is a file called new.txt which has permission -rw-r--r--, but when someone use chmod 777 new.txt the permissions are changed. Then how to get back the original permissions of new.txt if I do not know the previous permission.

I'm trying to have both MikTex and TexLive working on my Ubuntu Linux. Both the tex distros have been installed through apt-get. I know this is related to settings on the PATH variable. So what I did is:
Find TexLive executables location:
whereis texlive

@JourneymanGeek it's twice baked... in this method, you shape the dough into a block, bake on low temperature for ~30 min, take it out and let it cool down, then cut it into the shape you want, probably long cuboids, then bake it again at a high temperature for 10-15 min

idk about buttermilk, I have a feeling it's something I don't like at all by itself... I think I've only eaten it in soda bread... it's not even something you can buy as an ingredient here... but what you said about soaking reminded me of activated nuts... the first ones that came out contained dairy, maybe they were soaked in buttermilk too for the acidity... then they all went vegan in response to the market for nuts & heath food, and I think they just use salt water

but nuts have their own fat, so they become delicious without any fat being added haha

I have windows 7, then I installed ubuntu 18.04 LTS, and have grub to choose my os I want.
When I'd boot my computer to an eSata, and then restart and choose windows 7 on my computer I had an error 0xc000000f Info: An error occurred while attempting to read the boot configuration data

@Dale No, @Fabby normally works days and nights through until he finally falls asleep ... only when he wakes up and doesn't know who he is and where he is - then ... and only then - there's a (slightly) chance that he falls (drunken, because he learned from @SergiyKolodyazhnyy that vodka makes coffee taste like it should) into this chat room. So you have to wait and be extremely patient ! :D :D :D

In Ubuntu 16.04, when I powered on my computer, the drum roll sound would be played right before I was presented with the Login interface. After I upgraded to Ubuntu 17.10 the drum roll sound is no longer being played. I did some research on the web and tried the following, which enabled the drum...

@Fabby As you may know from my profile, I'm currently using Ubuntu MATE 16.04 LTS. Tested 18.04 LTS MATE. They are stable and fully functional. Taking foreign file-manager to the GNOME may cause issues. So I use native Caja on MATE. It has extra-pane and other well-designed features from Nautilus 2.32.

@Fabby as old-school user I do not use 3D compositing on it. But it is supported (trying to add picture here...). The main goal is Traditional desktop, not lightness. But yes, it works great on Atom with 2Gb of RAM and Haswell with 32Gb of RAM.

I've installed the raspberry pi version of kali linux. When trying to install something via apt-get install I get the error mentioned in the title.
The sd card I'm on is 32 GB so there should be plenty of space.
